The effect of radial swirl generator on reducing emissions from bio-fuel burner system
Mohamad Shaiful Ashrul, Ishak; Mohammad Nazri, Mohd Jaafar; A. Eldrainy, Yehia (Canadian Center of Science and Education, 2009-06)A liquid bio-fuel burner system with various radial air swirlers attached to combustion chamber of 280 mm inside diameter and 1000 mm length has been investigated. All tests were conducted using crude palm oil as fuel. A ... -
Effect of velocity variation at high swirl on axial flow development inside a can combustor
Mohamad Shaiful, Ashrul Ishak; Mohammad Nazri, Mohd Jaafar, Prof. Dr. (Penerbit UTM Press, 2014)The main purpose of this paper is to study the internal flow effect of varying the inlet velocities inside a combustor. The flow field inside the combustor is controlled by the liner shape and size, wall side holes shape, ... -
Experimental study on the production of CO-NO-HC emissions in the radial swirling flow combustion system
Mohamad Shaiful, Ashrul Ishak; Mohammad Nazri, Mohd Jaafar (Penerbit UTM Press, 2014)The main purpose of this paper is to evaluate the production of CO-NO-HC emissions while varying the swirl angle of curve vane radial swirler. Air swirler adds sufficient swirling to the inlet flow to generate central ... -
The influence of orifice insertion in radial swirling flow for low emissions combustion
Mohmad Shaiful Ashrul, Ishak; Mohammad Nazri, Mohd. Jaafar (Universiti Teknologi Malaysia (UTM), 2008-12)This paper presents the effect of inserting swirler outlet orifice plate of different sizes at the exit plane of the flat blade radial air swirler in liquid fuel burner system. Tests were carried out with three different ... -
Numerical analysis on the CO-NO formation production near burner throat in swirling flow combustion system
Mohamad Shaiful, Ashrul Ishak; Mohammad Nazri, Mohd Jaafar, Prof. Dr. (Penerbit UTM Press, 2014)The main purpose of this paper is to study the Computational Fluid Dynamics (CFD) prediction on CONO formation production inside the combustor close to burner throat while varying the swirl angle of the radial swirler. Air ... -
Numerical investigation of combustion performance utilizing envo-diesel blends
Mohamad Shaiful, Ashrul Ishak; Mohd. Amirul Amin, Arizal; Mohammad Nazri, Mohd Jaafar, Prof. Dr.; Norwazan, Abdul Rahim; Ismail, Azmi (Trans Tech Publications, 2013)Alternative fuel and renewable energy is needed to fulfill the energy demand of the world. The use of envo-diesel fuels for power generation seems a viable solution for the problems of decreasing fossil-fuel reserves and ... -
